In the Layer Order tab, which visualization will appear on top if X is listed first, Y second, and Z third?

The correct choice indicates that the visualization represented by X will appear on top in the Layer Order tab. In data visualization tools, the order in which layers are arranged often determines their stacking behavior—essentially which elements are displayed in front of or behind other elements.

When X is listed first, it signifies that it is the topmost layer. This means that any visual elements associated with X will be rendered above those associated with Y and Z. Layers are typically stacked in the specified order, with the first layer being the most prominent and the last being the base layer, obscured or overlapped by the layers above it.

This layering concept is crucial when designing visualizations to ensure that the most important information is easily accessible and discernible to viewers, as overlapping can impact the visibility of the underlying layers. Therefore, in this context, since X is first, it naturally becomes the top layer in the visualization hierarchy.
